The SanDisk Ultra is a 512GB microSDXC card sold with a full-size SD adapter, so the same card works in phones, tablets, drones, action cameras and laptops with an SD slot. It is a UHS-I card rated Class 10 and U1, which suits photos, 1080p video and moderate burst shooting rather than sustained 4K recording. SanDisk rates it for transfer speeds up to 120MB/s and backs it with a limited lifetime warranty. Against the Extreme and Extreme Pro lines it is slower and lacks V30/V60 ratings, but it is the simpler, cheaper way to add a large amount of storage.
